Yes you did.
Miltank, Tangela and Slowking will all wreck the tier. It's incredibly hard to break through them. (Especially Slowking)
Klinklang, Shelgon, Zweilous, Serperior and Jumpluff won't be that good. Klinklang is good if he manages to set up but he's walled by a lot, Shelgon will probably be okay, Zweilous is extremely slow but can wreck if he manages to get a hit in, and Serperior+Jumpluff are literally just trolls that don't have much use in the tier other then subseeding, and that's just an annoying strategy. Eel also has trouble against prepared teams, it'll probably be really good at the beginning though.
Also, Rotom-S would work better as a scarfer, para-flinching isn't very reliable. Mespirit would probably be used for sub cm sweeping, although there's also Dusion for that who will probably wreck in the tier too if you be careful of Sableye.
